tnRoePPointer

The parameter is available only when CPRI port is set to
structure-aware mode.  Specifies p-pointer value for
the fast C&M channel in CPRI link associated with the RoE
entity.  p-pointer defines the fast C&M channel region
(starting subchannel) inside the CPRI control word.
Based on CPRI rate and p-pointer value, the fast C&M
Ethernet rate is also defined.  Value = 0 means fast C&M
channel is not used in CPRI link.
              
This parameter can be modified only when roe is shutdown.
And the modification of this parameter may cause traffic
interrupt and need to modify it in both roe mapper and
demapper so that the new value can work.
              
1 set of mapper and demapper (ID = 66) is reserved for
handling fast C&M channel in CPRI link.  Native Ethernet
packet (instead of RoE packet) is used to transport fast
C&M channel content.  p-pointer value specifies the fast
C&M channel region inside the CPRI link control word.
RoE mapper then searches for the Ethernet packet content
(start with SSD sequence, end with ESD sequence) inside
this region and transports the entire Ethernet packet
content as is.  After reception of an Ethernet packet
into the associate demapper (buffer queue), demapper
plays out the Ethernet packet content from buffer queue
sequentially into the fast C&M channel region. Demapper
automatically inserts idle sequence (ie inter-packet gap)
between Ethernet packets into fast C&M channel.
              
Default value for this attribute is 0.
